Just the lack of processed ingredients, and abundant salt, sugar, and fat is going to make a huge difference. Not to mention whatever harm we suffer from the chemicals they put in our food. And microplastics.

Then beyond food. Living without everything being contaminated with lead and asbestos can’t be bad.

I’m not nostalgic for a primitive life. But industrial environmental degradation has been disastrous for health, even if it coincided with modern medicine (great for those who can get it).
